00:00 - 00:59 | Centre kaha par bola x square upon a minus b square is equal to 1 the tangent at any point on a straight line 2 x minus 3 Y is equal to zero and b is equal to zero at points q and r 2 CR is equal to a square + b square Solan Tata solution given equations are equation of hyperbola that is why square upon and the equation of the state line that is d x minus Y is equal to zero and X + Y is equal to zero equation of tangent in Param |

01:00 - 01:59 | parametric form to the given how popular is expecting theatre born A + Y 10 theta upon b is equal to 1 + market at equation 1 equation in this equation is lines so x minus a one can be x minus y we can put x is equal to a y be in this equation service get x is equal to a into 1 + sin theta upon cos theta and Y is equal to b into 1 + sin theta upon cos theta |

02:00 - 02:59 | keulen so for point are similarly X will be a into 1 minus sin theta divided by cos theta and Y is equal to minus b into 1 minus sin theta cos theta from this cq will be equal to under root main into 1 + sin theta theta whole square plus a into 1 + sin theta upon cos theta |

03:00 - 03:59 | for scared NCERT will be baked into 1 minus sin theta upon cos theta whole square + 8 into 1 minus sin theta upon cos theta whole square from this to CR will be equal to a square + b square has to thank you |
